Description
Изобретение касаетс устройств дл подачи консистентной смазки в подшипниковые узлы качени электродвигател и дл удалени отработанной смазки.The invention relates to devices for delivering grease to motor bearing units of the electric motor and for removing spent lubricant.
В известных устройствах подобного типа смазка вытесн етс из полости подшипника, при этом отработанное масло попадает в полость передней крышки подшипника и удал етс наружу.In known devices of this type, the lubricant is expelled from the bearing cavity, while the waste oil enters the cavity of the front bearing cap and is removed to the outside.
В данном изобретении на валу обеих сторон подшипника качени посажены два диска с расположенными снаружи лопатками, а в нижней части подшипникового щита устроено гнездо, в котором расположен плунжер дл возврата смазки, вытесн емой из полости подшипникового узла, обратно в эту полость, и автоматического дозировани количества смазки в последней, а также дл принудительного удалени излишков смазки через указанное гнездо путем выдвижени плунжера.In the present invention, two discs with blades located outside are mounted on the shaft of both sides of the rolling bearing, and in the lower part of the bearing shield there is a slot in which a plunger is located to return the lubricant displaced from the bearing assembly cavity back into this cavity lubrication in the latter, as well as to forcibly remove excess lubricant through the specified socket by extending the plunger.
На чертеже изображено устройство дл подачи консистентной смазки в подшипниковые узлы качени электродвигател и удаление отработанной смазки.The drawing shows a device for supplying grease to motor bearing units of the electric motor and removing used grease.
На валу / с обеих сторон подшипника качени 2 штифтами 5 жестко укреплены два диска 4 с расположенными снаружи лопатками 5, отбрасываюш .ими вытесн емую из полости подшипника смазку обратно в эту полость. Этим обеспечиваетс уплотнение подшипника и автоматическое дозирование смазки в полость подшипника.On the shaft / on both sides of the rolling bearing 2 pins 5 are rigidly fixed two discs 4 with blades 5 located outside, the lubricant being pushed out of the bearing cavity back into this cavity. This ensures the bearing is sealed and the lubricant is automatically dispensed into the bearing cavity.
В нижней части подшипникового щита устроено гнездо 6, в котором расположен плунжер 7, предназначенный дл удалени смазки путем его выдвижени .A seat 6 is arranged in the lower part of the bearing shield, in which the plunger 7 is located, designed to remove the lubricant by extending it.
Нредлагаемое устройство прошло промышленное испытание на Харьковском электротехническом заводе.The proposed device passed an industrial test at the Kharkov Electrotechnical Plant.
